THE CANADIAN ENTOMOLOGIST 161 



anterior knees and all the tarsi yellowish-brown; wings hyaline; marginal and 

 stigmatical veins black; a brown spot basad of stigma. 



Male. — Length 4.25 mm. Except for usual differences, like female. Venter 

 without yellow. 



Type-locality. — Syracuse, New York. Described from two females and 

 five males reared from Hicoria glabra by M. W. Blackman and H. H. Stage and 

 under their numbers H-171 (type), H-114 (allotype), H-955, H-134, H-892, 

 H-1367 and H-212. 



Type.— C3.t. No. 22093, U. S. Nat. Mus. 



Ecphylus hicoriae, new species. 



Readily distinguished from related American species by its colour and 

 sculpture. 



Female. — Length to apex of abdomen 3 mm.; length of ovipositor 2.5 mm. 

 Face granular and with irregular transverse, raised lines; frons and vertex with 

 distinct transverse striae; posterior orbits smooth; postocellar line about half 

 as long as ocellocular line; antennae 27-jointed, the third joint distinctly shorter 

 than the fourth; pronotum with lateral angles prominent; prescutum punctured, 

 and with a median impressed longitudinal line; notauli foveolate; scutellum 

 without sculpture; propodeum coriaceous, reticulate in apical dorsal middle, a 

 faint dorsal median longitudinal carina and a transverse carina at top of posterior 

 aspect; recurrent interstitial with intercubitus; first tergite one-fourth longer 

 than apical width, with distinct longitudinal striae, these more prominent laterally 

 so there is a triangularly-shaped median area which is not so coarsely striate, 

 remaining abdominal segments smooth, polished. Black; abdomen beyond first 

 segment rufous; basal joints of antennae and legs yellowish-ferruginous; pro- 

 notum anteriorly and lower part of mesepisternum rufous (may not be constant) ; 

 wings hyaline; venation dark brown. 



Male. — Length 3 mm. Agrees with female except for usual differences. 



Type-locality. — Syracuse, New York. Described from three females and 

 one male reared from Hicoria glabra by M. W. "Blackman and H. H. Stage, and 

 recorded under their numbers H-972 (type , H-956, H-947 and H-118a allo- 

 type). 



Type.— Cat. No. 22030, U. S. Nat. Mus. 



In the male and in one female the frons are partly ferruginous. 



Heterospilus blackmanni, new species. 



Because of the colour and length of ovipositor this new species would be 

 grouped with consimilis Ashmead, but the sculpture is quite different from 

 that species. 



Female. — Length to apex of abdomen 2.55; length of ovipositor 2.5 mm.; 

 length of abdomen 1.25 mm. Head smooth, polished; ocelli in nearly an equi- 

 lateral triangle; inner margins of eyes parallel, the distance between them 

 somewhat greater than their length; antenna, 20-jointed, the third joint about 

 one-fifth longer than the fourth; scutum and prescutum shining, practically 

 without sculpture; notauli well defined, not foveolate; suture in front of scutellum 

 finely foveolate; scutellum smooth, shining; dorsal lateral areas of the propodeum 

 polished, median carina distinct; posterior face of propodeum finely coriaceous; 

 first tergite about one-sixth longer than apical width, with distinct longitudinal
